How to make the three-dimensional pattern on the surface of the thermos cup?

As people’s living requirements continue to improve, daily necessities have begun to become more and more personalized, even the insulated water cups that people use every day but don’t care about. The surface of the thermos cup ranges from stainless steel original color to spray paint and plastic spray to various pattern printing.

The pattern printing process is also constantly upgraded with the different types of patterns. Patterns are no longer limited to flat printing processes and monochrome printing processes. Currently, not only color high-definition printing can be achieved, but also luminous pattern printing, as well as three-dimensional relief printing, etc.

What printing process is used to achieve three-dimensional relief effect pattern printing? Currently on the market, the following printing processes are usually used to achieve three-dimensional relief pattern effects:

1. 3D printing technology. 3D printing can achieve repeated printing on some pattern details through file settings. Since the ink used in 3D printing is quick-drying and is made of hard glaze-like material, repeated printing will not cause patterns. Collapse, because the ink dries quickly, allows the printed coatings to stack up for a three-dimensional effect.

2. Water sticker technology. Water sticker technology can also achieve pattern relief effects. The method of implementation is similar to 3D printing. After plate making, the objects are positioned and printed repeatedly, and a three-dimensional effect is formed through multiple stacks. However, due to current printing machine processing technology, accuracy and positioning issues, the water decal pattern cannot be as detailed and realistic as the 3D printed pattern. The water decal process can only be used for relatively large color blocks, and the color bars are repeated. When printing, if the lines are too thin or the details are exquisite, precise positioning cannot be achieved and repeated printing cannot be achieved.

3. Corrosion process. The corrosion process is also called etching process. The pattern part is leaked through blocking, and then wiped with acid multiple times. The more times, the greater the depth of corrosion, thus creating an uneven pattern effect on the surface. In order to make the other side not too monotonous, oil filling and coloring processes were added later to enrich the pattern levels. However, the patterns produced by this production method are mostly thick line texture patterns, which cannot be as realistic as 3D printing and decal patterns. Effect.rough multiple stackings.
